Method for producing polymer electrolyte molded article, polymer electrolyte material, polymer electrolyte membrane, and polymer electrolyte fuel cell

A polymer electrolyte molded article comprising an ionic group-containing polymer in which a crystallization peak is recognized by measurement of temperature modulation differential scanning calorimetry,

• wherein crystallinity measured by wide angle X-ray diffraction is less than 0.5%, and
• the ionic group-containing polymer is a polymer comprising at least one repeating unit selected from a group consisting of repeating units represented by the general formulas (T1-1) to (T1-6):
• wherein Z1and Z2 represent an organic group containing an aromatic ring selected from:
• a phenylene group, a naphthylene group, and a biphenylene group;
• at least a portion of Z1 and Z2 has an ionic group selected from:
• a sulfonic acid group, a sulfoneimide group, a sulfuric acid group, a phosphonic acid group, a phosphoric acid group, and a carboxylic acid group;
• a and b each independently represents 0 or a positive integer, provided that a and b does not simultaneously represent 0;
• and
• the organic group represented by RP is a group selected from:
• a methyl group, an ethyl group, a propyl group, an isopropyl group, a cyclopentyl group, a cyclohexyl group, a norbornyl group, a vinyl group, an allyl group, a benzyl group, a phenyl group, a naphthyl group, and a phenylphenyl group.
